1 cup sourdough discard (unfed, straight from the fridge)
1 cup all-purpose flour (plus more for dusting)
1 cup shredded mozzarella cheese
1/2 cup grated Parmesan cheese
2 tablespoons olive oil
1 teaspoon baking soda
1/2 teaspoon garlic powder
1/2 teaspoon salt
Instructions
Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a large mixing bowl, combine the sourdough discard, all-purpose flour, shredded mozzarella cheese, Parmesan cheese, olive oil, baking soda, garlic powder, and salt. Mix until a shaggy dough begins to form.
Use your hands to bring the dough together into a cohesive ball. The warmth from your hands helps melt the cheese slightly.
Turn the dough out onto a lightly floured surface and knead for 1-2 minutes until it becomes smooth and elastic. If too sticky, dust with a bit more flour.
Shape the dough into a rectangle using your hands. Using a rolling pin, roll the dough out to about 1/4-inch thickness into a 10×12 inch rectangle.
Cut the dough into even strips, about 1-inch wide, using a pizza cutter or sharp knife. You should get approximately 12 breadsticks.
Place the breadsticks on the prepared baking sheet, leaving about 1/2-inch space between each one.
Bake for 12-15 minutes, or until they are deeply golden brown with crispy, bubbling cheese. Watch closely after 12 minutes.
Remove from oven and let cool for 2-3 minutes on the baking sheet before serving warm with your favorite dipping sauce.
Notes
Use sourdough discard straight from the refrigerator without feeding or warming it first.
For extra flavor, brush breadsticks with melted garlic butter immediately after baking.
Don’t roll dough thinner than 1/4-inch or breadsticks will become too crispy and lose their soft center.
Pre-shredded cheese works fine, but freshly shredded mozzarella from a block melts better and creates a crispier crust.
